To all whom t mag/concern,.-

Be it known that L'CHARLESM. GREY, a citizen of the United States of America, resid? ing at New York, in thecounty of New York and State of New York, have'invented certainv new and useful Improvements in Rolling- Mills; andi hereby declarel the following to be a full, clear, and'exatdescription of the.

invention, such as will enable others skilled in the art to which it pertains to make andv use the same. f Y .Y i

This invention relates to improvements in mills or apparatus for rolling metallic beams,

girders, and structural work generally. This invention pertains more especially to' a mill whichvis adapted for use in rolling a auged beam or bar fed through the mill, with its web orbody portion arranged horizontally, and comprises, first, two horizontal rolls arranged one above the other and in the same ,vertical plane and in position to operate upon and in position to operate upon and cover-the outer sides of the heads or flanges of the blank or work and carried by slides which'ar'c adj ustable toward or from each other, so as to render the said side rolls adjustable apart; third, two straightening-bars arranged at opposite sides, respectively, of the path of the blank or work at one side ofthe horizontal rolls and operated as required to gradually and intermittently effect astraightening of the blank or product; fourth, two side guides arranged at opposite sides, respectively, of the path of the blank or work at the opposite side of the horizontal rolls; fifth, a shaft operatively connected with screws instrumental in efecting the adjustment of the upper horizontal roll; sixth, another shaft arranged parallel with the said screw-operating shaft and operatively connected with the aforesaid sideyroll-carrying slides; seventh, powers-transmitting means whereby Variable motion is transmissible from one to the other of the said shafts, so that the adjustable horizontal webreducing roll and the upright flange-reducing side rolls are simultaneously shifted inwardly during a readjustment of the said rolls to reduce the "passage formed between the rolls between successivepasses ofthe blank or work i through the mill; eighth, means whereby the upright side rolls are shiftable vertically or endwise, and, ninth, means whereby the shifting of the said side rolls vertically or endwise 1^ is sim ultaneous with and in the same direction as and entirely dependent upon the vertical xshifting of the adjustable horizontal roll.

Y The primary object of my present invention is to provide a construction whereby not only callywithont incurring any interruption in the operation of the mill, but the upright side rolls are shiftable vertically simultaneously with the adjustment of the adjustable horifzontal roll and the vertical shiftability or adjustmentnof the said side rolls is wholly de- `jpendent upon the adjustment of the adjustyable horizontal roll, so that an accurate maintenance of the said side rolls vertically central relative to the blank or work to be operated upon bythe said side rolls is insured "and an adjustable horizontal roll having the ,diametricallylargest necks or tru unions practicable withoutinterference between the said necks or trunnions and the side rolls is'accommodated.

Another object of this invention is to provide such improvedl arrangement and combinations of parts that the means employed in effecting the lateral adjustment of the up'- right side rolls and the means instrumental in vertically or endwise shifting the saidvside 9 rolls can be operated independently of each other.

With these Objects in view and to thev end V of realizing other advantages hereinafter ap- `pearingthis invention consists in certain fea' roo tures of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a top plan of a mill embodying my invention and portions are broken away and in section in this figure to more clearly show the con struction. Fig. II is a side elevation of the mill, partly in section. Fig. III is a top plan of a portion of the mill, largely in section, taken centrally between the upper and lower ends of one ofthe side rolls D. side elevation ot a portion of the mill, largely in section, on line IV IV, Fig. III, looking in the direction indicated by the arrow. Fig.V is an elevation, largely in section, online V V, Fig. III, looking in the direction indicated by the arrow.

My improved rolling-mill comprises an upper horizontal roll B, a lower horizontal roll B2, and two vertical side rolls D and D, arranged at opposite ends, respectively, of the said horizontal rolls and centrally between the axes of and at a right angle to the said horizontal rolls. The roll B is arranged above and transversely of the upper side of the path of the blank or work in position to operate upon the upper side of the web of the blank and upon the inner sides of the flanges or heads ot the blank above the web.

The roll B2 is arranged below and transversely of the path of the blank in position to operate upon the lower side of the web and upon the inner sides of the heads or anges below the web.

The two side rolls D and D are arranged at opposite sides, respectively, of the path of the blank in position to operate upon the outer side of the adjacent tlange or head of the blank.

The blank or work C is shown in position in Fig. II.

The rolls B and 'B2 are practically of the same diameter and rot-ated in opposite directions, respectively, and the blank or work is given as many passes through the mill as are required to complete the rolling or shaping of the work, and the blank is of course suitably heated preparatory to its introduction into the mill and fed through the mill with its web arranged horizontally.

An engine-shaft 4 (see Fig. II) is operatively provided with a gear 5, which is operatively connected in any suitable manner with a neck or trunnion b2 ot' the bottom web-reducing roll B2. The gear 5 meshes with a diametrically corresponding gear 6, which is operatively connected in any approved man-y ner with the adjacent trunnion b of the top web-reducing roll B.

The bottom roll B2 is suitably supported from two housings G and G, which are arranged a suitable distance apart at opposite sides, respectively, of the path of the blank.

It is obvious that for work of the character indicated one of the web-reducing rolls must be adjustable vertically and the side rolls Fig. IV is a D and D must be adjustable apart. In the mill illustrated the top roll B is adjustable toward and from the bottom roll B2. It is obvious also that the adjustable rolls B and D and D are at the commencementot the operation of the mill set as required for the first pass of the heated blank.

The adjustment of the rolls B and D D relative to the path of the blank or work is effected simultaneously, and the side rolls D D in adjusting them apart simultaneously with the adjustment ofthe top roll are moved more rapidly than the top roll in order to avoid long crop ends and torn or cracked flange edges on the finished product.

Each housing G near its lower end, adjacent to the adjacent trunnion of the bottom web-reducing roll B2,is provided with brackets g, which form a slideway for and support the outer end portionor member d of a slide H, whose inner end portion or membere carries one ofthe side rolls D. Both slides II and II are adjustable toward or from each other, and the two rolls D and D are therefore adjustable apart.

Each slide I-I is operatively connected at its central portion with a screw H2, arranged parallel with the travel of the said slide. The said screw H2engages a correspondinglythreaded nut I, (see Fig. IIL) rigidly secured within a recess H', formed in the central portion of the outer end portion or member d of t-he slide. The said member d is connected with but has an adjustment toward and from and independently ot' the roll-bearing inner end portion or member e of the said slide, which member e is supported as will hereinafter appear. The said outer slide member d carries the thrust-bearing for the side roll D, carried by the said slide, and the said thrust-bearing comprises two large Vertical rollers J and J, arranged a suitable distance apart at the outer side of and engaging the said side roll. Two bolts or rods h are attached to the inner or roll-bearing slide member e. The space had between the two slide members d and e accommodates the adjustment ot the outer slide member CZ upon the said rods h toward the inner slide member e. The adjustability ot' the slide member d accommodates the taking up of any wear between the said side roll D and the engaging rollers J and the maintenance of the rollers in contact with the roll, and the slide member d is retained in the adjustment required to hold its rollers in contact with the roll by nuts h2, which engage threads formed upon the said rods h at the outer end of the said slide member. Each rod h extends into a recess e', formed in the inner or roll-bearing slide member e, and the said rod is provided within the said recess with a head t, and the said recess is correspondingly shaped to receive the said head with suiticent closeness to prevent detachment ot' the rod from the said slide member by pulling endwise upon the said rod.

IOO

IIO

The recesses e of a slide member e extend vertically of the said slide member and are open at their upper ends to accommodate the introduction of the engaging rods Zt intoY the said slide member e during the assemblage of the parts. It will be observed, therefore, that the inner and roll-bearing` slide member e of each slide is hitched to or connected with the outer and roller-bearing slide member cl of the said sldein such amanner ythat the said inner slide member is shifted simultaneously with the said outer slide member, when the two slides H and H are adjusted apart without interfering with the'vertical shiftability of the said inner `slide member independently of the said outer slide member and without detaching thesaid inner slide member from the said outer slide member during the vertical shifting of the said inner slide member.

Each slide-operating screw H2 extends from the connected slide H outwardly through-a yoke-forming beam or piece G2, which connects together and is secured to the two legs of the housing which supports the said slide. Two collars H3 andHg, which arel fixed or formed upon the screw at opposite sides, respectively, of the said Ipiece G2, prevent endwise movement of the screw during the rotation of the screw.

. It is obvious that each slideHand the roll supported thereby are adjusted toward or from the pair of .horizontal rolls B B2, according as the connected screw7 H2 is turned in the one direction or the other.

Two upright screws LL (see Figs. I and II) engage correspondinglythreaded nuts L2, fixed or formed in the tops of housings G G. Saddles Z (see also Fig. V) are interposed between the lower ends of said screws and the trunnionsof the top roll B', which tru'nnions have bearing in boxes Z', which rest vupon vertically-movable frames :or structures Z2, engaged and held in the desired adjustment by the pistons Z2 of hydraulic cylinders Z4, and therebysupporting the roll at the desired elevation controlled by the screws L.

The mechanism employed for rotating the screws L and H2 is shown tofbe as follows: Upon the upper end or portion of eachscrew L is operatively mounted a worm-wheel L', which meshes with a worm M', formed upon a suitably-supported horizontallyarranged shaft M, which is arranged at the top of and above the housings G. The upper ends of screws L areangular in cross-section and extend through andare -shiftable endwise of corresponding' holes in the central portions of the engaging wheels L' without interrupting operative connection between the said wheels and screws. The shaft M is suitably driven in the one direction or the other, according as the screws L, and consequently the top roll B', are to be elevated orlowered.

Upon the outer end of each screw H2 is op-V eratively mounted a worm-wheelH5, which meshes with a worm h5, formed upon a suitably-supported upright shaft h4. Eachvshaft a h4 is operatively provided at its upper end with a bevel-gear h2, which meshes with a bevel-gear N6, operatively mounted upon a shaft N, which is suitably driven in the one or the other direction, according as the slides H H, and consequently the yside rolls D D,

are shifted toward or from each other.

Bottom and top guides (not shown) for preventing vertical displacement of the work 4during the operation of the millshould be provided; but such guides form no part of the present invention and are therefore not illustrated in' this application. 1

It is obvious that, as already indicated, the

top web-reducing roll B', and with it the tia-nge- A largest work-receiving passage between the said rolls during the reducing operation upon the blank and said passage, is rendered smaller preparatory to each successive pass of the work,and the rolls after the work has had its finishing pass are again adjusted to enlarge the work-receiving passage between them, as required for another blank.

Two side guide-forming bars r r for the work (see Figs. I and III) are arranged at one side of the rolls B' and B2 at opposite sides, respectively, of the path ofthe blank or work, and two side guide-forming and work-straightening bars R R are arranged at the other side of the said rolls at opposite sides, respectively, of the path f the blank. The bars R R extend longitudinally of the said path and are pivoted vertically near their inner ends, as at R', to the different housings G G, respectively, so that the said ba rs R are capable of being swung horizontally on their pivotal bearings toward or from each other. Bars-R R near their outer or free ends are operatively connected with each other (see Figs'. I and Il) by a horizontally-arranged shaft T, which extends transversely of and belowvthe path of the blank through the lower portions of the bars RR. A right-handed screw T' is formed upon the shaft T at the outer side of one of the bars .,R, and a lefthanded screw T2 is formed upon the said shaft at the outer side of the other bar R. I Screws T. and T3 are operatively engagedv by two `nuts T2 and T4, respectively. The said nutshave bearing in and are arranged to slide endwise of lugs G4, formed upon the housings ICO G, and each bar R is operatively connectedv with one of the said nuts, andV in thefmill illustrated the lower` portion of each bar R loosely embraces the shaft and engages a ref cess T5, formed in the connected nut. The

gear N10, operatively mounted upon the said shaft N.

Guides fr r extend longitudinally of the path ofthe blank or work and are pivoted verv' tically at or near their inner ends, as at r', to

the different housings G and G, respectively, so that the said guides are capable of being swung horizontally on their pivotal bearings toward or from each other upon the operation of a horizontally-arranged shaft if, which extends transversely of and below the path nof the blank through the lower portions of the guides rr. A right-handed screw t' is formed upon the shaft t at the outer side of one of the said guides r, and a left-handed screw t3 is formed upon the shaft at the outer side of the other guide o". Scl'ews t and 153 are operatively engaged by two nuts t2 and 4, respectively. Said nuts t2 and t4 have bearing in and are arranged to slide endwise of lugs g4, formed upon the housings G, and each guide 'r is operatively connected with one of the said nuts, and in the mill illustrated the lower portion of each guide r loosely embraces the shaft 15 and engages a recess 255, formed in the connected nut. Shaft t is operatively provided at one end with a bevel-gear t, which meshes with a bevel-gear 157,0peratively m ounted upon a suitably-supported shaft t8, which is arranged horizontally and at right angles to the shaft t. Shaft t8 extends from adjacent the shaft toward and into suitable proximity to the shaft T and adjacent the shaft T is operatively provided with a bevel-gear t9, which meshes with a bevel-gear T9,fixed to the shaft T.

By the construction hereinbefore described it will be observed that the side guides r, the work-straightening bars R, andjthe side-rollcarrying slides H are all operatively connected with one and the same shaft N, and consequently both guides r, both bars R, and both side rolls D are simultaneously adjusted apart during the operation of the said shaft.

The shaft N is intel-geared at one end, as at o, with the shaft 0 of an engine or motor o2, only diagrammatically shown. (See Figs. I and Il.) A sleeve p is slidably and operatively mounted upon and adjustable endwise of the shaft N. Three spur-gears p', p2, and 193 are formed upon the sleeve p at suitable intervals longitudinally of the sleeve and differ in diameter or number of teeth. The relative arrangement of the said gears is such that the middle-sized gear p2 is arranged centrally between the largestp and the smallest p3 of the said gears.

A sleeve u is loosely mounted upon the shaft M adjacent to the sleeve p on the shaft N. The sleeve u has as many gears formed thereon as there are gears on the sleeve 19. Hence the sleeve u has three gears u', u2, and ug, which are arranged at suitable intervals longitudinally of the said sleeve and differ in diameter or number of teeth. The relative arrangement of the gears 25,112, and tts is such that the middle-sized gear u2 is arranged cenil. relative to the arrangement of the gears of the sleeve p is such that the largest, middlesized, or smallest of the gears of the sleeve p shall be rendered operative and brought into mesh with the smallest, middle sized, or largest, respectively, of the gears of the sleeve u, according as the sleeve p is in its extreme position in the one direction, in its intermediate position, or in its extreme position in the opposite direction endwise of the shaft N, and when any gear of the sleeve p is in mesh with a gear of thesleeve u the remaining gears of the sleeve u are out of mesh with their companion gears on the sleeve p.

Means for securing the gear-bearing sleeve lo in the desired adjustment comprises a pin s, which extends through a hole p4 in the said sleeve into engagement with any one of three holes N', N2, and N3, formed in the shaft N at suitable intervals longitudinally of the said shaft. The arrangement of the said holes relative to the different positions of the sleeve p is such that the holep4 in the sleeve shall be in registry with the hole N or With hole N2 or with hole N3, according as the said sleeve is adjusted with its largest gear p' or with its middle sized gear p2 or with its smallest gear p3 in an operative position. Obviously only the pin s has to be withdrawn from the engaging hole in the shaft N preparatory to a readjustment of the sleeve p, and the said sleeve is then secured in its readjustment by sliding the pin into the shafts hole which is then opposite the said pin.

The operative connection between the sleevep and the shaftN is formed, preferably, by the well known means of groove and feather, as at fu, which feather extends far enough longitudinally of the range of adjustment of the said sleeve to maintain operative connection between the said sleeve and the said shaft in any adjustment of the said sleeve.

By the construction hereinbefore described it will be observed that motion is transmitted from the shaft N to the shaft M through the medium of the gear-bearing sleeves p and u; but the sleeve u, as already indicated, is loosely mounted upon the shaft M,and in order to transmit power to the shaft M through the medium of the sleeves p and 'tt operative connection must be established between the sleeve u and the said shaft M, and the means employed for thus establishing operative connection between the shaft M and the sleeve u comprises a clutch which has one of its members w formed upon the said sleeve and has its other member to2 slidably and operatively mounted upon the shaft M by the wellknown means of groove and feather w. A suitably-applied lever w3 engages an annular groove w, formed in the clutch member 102, and obviously operative connection between the shaft M and the sleeve u is estab- IOO IIO

IIS

lished or interrupted, according as the slidable clutch member to2 is actuated into or out of operative engagement with the companion and relatively stationary clutch' member w. The clutch member w' Ais formed, preferably, upon one end of' the-sleeve u, and the shaft M is provided next adjacent to the opposite end of the sleeve with a collar M7, which prevents endwise displacement of the said sleeve 'during the actuation of the slidable/clutch member w2 into engagement with the relatively stationary clutch member w'. It will be observed, therefore, that by the provision of the two parallel shafts M and N and the mechanism hereinbefore described for transmitting power from the primarily-driven shaft N to the secondarily-driven shaft and for changing the speed of the latter relative to the speed of the primarily-driven shaft the travel of the pair of side rolls D, pair of side guides r, and pair of work-straightening bars R during the adjustment apart of the members of the said pairs relative t0 the' travel of the top Webreducing roll during the adjustment of the said top roll relative to the bottom web-reducing roll can be readily changed without necessitating the removal of any gearing or otherwise incurring material interruption in the operation of the mill.

Of course the travel of the side rolls D during their adjust ment apart is preferably more rapid than the travel of the top web-reducing roll during the adjustment of the saidtop roll -relative to the bottomweb-reducing roll.

The travel of the side guides rduring the adjustment apart of the said guides is preferably about the same as the travel of the sideroll-carrying slides H during the adjustment apart of the side rolls'. The travel of the work-straightening bars R during the adjustment apart ofthe said bars is preferably more rapid than the t-ravell of the side guides; but the desired travel ot' the side-roll-carrying slides H, work straightening bars R, and side guides r can be readily attained by properly relatively7 proportioning the gearing instrumental in transmitting power from the shaft N to the said side guides r,workstraight ening bars R, and side-roll-carrying slides H; but the travel of the said side-roll-carrying slides H, work-straightening bars R, and side guides r during their adjustment will be changed simultaneously and correspondingly relative to the travel of the top Web-reducing roll upon changing the relative speeds of the shafts N and M. For instance, as illustrated, the smallest gear @t3 of the sleeveuis in mesh with the largest gear p' of the shaft p, so that a readjustment of the sleeve p to bring its intermediate gear 'p2 intomesh with the intermediate gear 'n2 of the sleeve u, which gear u2 is larger diametrically than the gear p2, will result in a dierence between the speeds of the shaftsNandM,andthespeed ofthe shaft N will then be greater relative to the speed of the shaft M, and consequently the travel of the and the Work-straightening bars R d'uring'a readjustment of thesaid work-straightening bars R, side guides r, and side-roll-carrying slides H will then be correspondingly greater than the travel of the top web-reducing roll duringa readjustment of the said top roll. Obviouslyupon a readjustment of the sleevep to bringthe'smallestgearpofthesaid sleeveinto mesh with the largest gear u of the sleeve u thedifference between the speeds of the shafts N- and M in favor of theshaft N will be stilll the' shaft M, and thev shaft Nican be rotated independently of the vshaft M. A simultaneous adjustment of the side rolls, side guides, and work-straightening'bars can then be effected independently of the adjust-ment of the adjustable web-reducing roll as may be required in setting or relatively adjusting the adjustable work-engageable parts of the'mill preparatory to the commencement of the operation of the mill.

The legs of each housing G are connected at the bottom of the said housing by a web g', whichV extends in under and supports the adjacent neck or trunnion of the bottom webreducing roll, as shown very clearly in Fig. V, and extends, of course, in under the inner endvportion or member e of the slide H, which supports or carries the side roll D, which is arranged above the said neck or trunnion, as shown also in Figs. III and lV, and two blocks `y are interposed between the said slide member e and the aforesaid web at opposite sides, respectively, of the said neck or trunnion,v and the said blocks form slideways'for the said slide member.y lhelower surface of each blockyslopes upwardlyand outwardly toward the outer endof the slide member e, which rest-s upon the said block and engages a correspondingly-sloping seat formed upon the web g. The said seat is formed, preferably, by a plate lo, which rests upon the correspondingly-sloping bottom of a recess g2, formed in the web g of the housing which supports the' said slide. The said blocks y form, therefore, wedges, interposed between' the lower surface of theinner end portion or member e of the said'slide H and the web g' of the housing which supports the said slide, and the said member of the said slide and consequently the roll borne by the said slide member are elevated or lowered, according as the said wedges y are actuated endwise in the onedirection or the other, and the importance of the vertical shi'ftability of the said slide member independentlyofthe outer slide member side-roll-carryin'g slides H, the side guide r, i of the said slide is therefore obvious. -The IOC ITD

side rolls D should be kept central vertically relative to the blank or work being operated upon, so as t'o always wholly cover the outer sides of the heads or flanges of the said blank, and the said rolls are adjusted vertically preparatory to the commencement of the operation of the mill to bring them central vertically relative to the path of the said blank. The operation of the wedges y] is effected by an operative connection between the said wedges and the top web-reducing roll, so that the inner slide members e, and consequently the side rolls, are during each readjustment of the said top roll shifted vertically as required to maintain the said rolls central with the path of the blank and to accommodate the employment of a top roll having the diametrically largest necks or trunnions practicable.

Preferably each wedge y, as shown in Figs. III, IV, and V, is provided upon its outer side with two lugs y', which engage opposite sides, respectively, of a vertically-arranged internally-screw-threaded union sawhich embraces and couples together the adjacent correspondingly externally-threaded ends of the two sections 12 of an upright of a frame Z2, which is instrumental, as already indicated, in supporting the top web-reducing roll B', and the said union has the external contour required to form two vertically and reversely arranged wedges arranged between the aforesaid lugsthat is, each upright of each frame Z2 is provided centrally between its ends with two upright wedges at', which are reversely arranged snugly between the lugs y', formed upon and projecting from a wedge y. One of the said wedges Qa', as shown very clearly in Fig. IV, tapers downwardly, therefore, and engages the inner of the said lugs y',whereas the other of the said wedges a" tapers upwardly and engages the outer of the said lugs. Hence during the descent of the uprights 12 ofthe frame Z2 during the lowering of the top roll B the downwardly-tapering wedges ai will operate to actuate the wedges y endwise toward the lower ends of or adown the sloping seats 7c, and thereby permit the inner end portions or members e of the` slides H, and consequently the side rolls D, to lower by gravity without, however, otherwise shifting the said slide members e and rolls D and without interfering with the capability of the said rolls to be adjusted laterally independently of the operation of the said wedges, and the upwardly-tapering wedges a," move idly during and thereby accommodate the operation of the downwardlytapering wedges During the ascent of the frames Z2 to elevate the top roll B the upwardly-tapering wedges of the said uprights will operate to actuate the wedges y endwise toward the upper ends of or up the sloping seats 7c, and thereby result in an elevation of the inner end portions or members e of the slides H, and consequently the side rolls D, without, however, otherwise shifting the said slide members e and rolls D and without interfering with the capability of the said rolls to be adjusted laterally independently of the operation of the wedges, and the downwardly-tapering wedges at move idly during and thereby accommodate the operation of the upwardly-tapering wedges m'.

The web g of each housing G is of course suitably slotted, as at g3, to accommodate the location of the frame l2, whose uprights eX- tend through the said web.

It will be observed that by the construction hereinbefore described the wedges operate as required to shift the engaging wedges y in the direction required to lower or elevate the slide members e, and consequently side rolls D, according as the ltop web-reducing roll B is lowered or elevated and that therefore the endwise or longitudinal shiftability of the side rolls is dependent entirely on the adjustment of the top roll laterally toward and from the path of the blank or work and that the side rolls D are shifted endwise simultaneously with and in the same direction as the top roll B during each readjustment of the said top roll and that the means employed in shifting the said side rolls D vertically or endwise and the means instrumental in adjusting the said side rolls laterally are capable of being operated independently of each other.

means whereby the operation of the said wedge-shifting meansis caused to be simul- Jtaneous with and dependent on the adjustment of the horizontal roll, and the arrangement of the parts being -such that during a readjustment of the said horizontal roll the upright roll moves down or up according as the horizontal roll is lowered or elevated.

8. The combination, with a vertical or up-v right reducing-roll arranged to operate upon one portion of the blank or work; another reducing-roll arranged in a horizontal plane in position to operate upon another portion of the blank or work and adjustable vertically; a vertieally-shiftable member arranged below and bearing the upright roll; and a bottom bearing below the said vertically-shift.- able roll-bearing member, of"means.instru mental in shifting the said'roll-bearing member vertically and interposed between the said roll-bearing memberand theA aforesaid bottom bearing, and means whereby the operation of the said shifting means is caused to be simultaneous with and dependent on the adjustment of the horizontal roll, and the arrangement of the parts being such that during a readjust-ment of the said horizontal roll the upright roll moves down or up according as the horizontal roll is lowered or elevated.

9. In a rolling-mill of the character ndicated, an endwise-shiftable laterally-adjustable upright reducing-roll arranged to operate upon one portion of the blank or work, means instrumental in eiecting the lateral adjustment of the said roll, a shaft operatively conneeted with the said roll-adjusting ICO IIO

' shifting mechanism, means whereby power is transmitted from one to the other of the said shafts and whereby the relative speeds of the said shafts can be changed so as to render changeable the ratio of the distance which one of the said rolls is laterally adjusted to the distance which the other roll is laterally adjusted during a readjustment of the said rolls, and means whereby the endwise-shiftable roll is shifted endwise simul- A taneously with and in the same direction as the other roll is adjusted.

lO. The combination of a roll arranged transversely of the path of the blank or work in position to operate upon one side of the web and upon the inner sides of the heads or flanges ofthe blank or work, another roll arranged transversely of the aforesaid path in position to operate upon the opposite side of the web and upon the inner sides of the heads or flanges and adjustable toward or from the first-mentioned web-reducing roll, mechanism instrumental in effecting the adjustment of the adjustable web reducing roll, a shaft operatively connected with the said mechanism, endwise-shiftable rolls arranged to operate upon the outer sidesv of the flanges or heads of the blank or work and adjustable apart, means for adjusting the last-mentioned rolls toward or from each other, another shaft parallel with the firstmentioned shaft and operatively connected with the last-mentioned roll-shifting means, means whereby the relative speeds of the said shafts can be changed so as to renderchangeable the ratio of the distance which the adjustable web-reducing roll is shifted to the distance which the exclusively flange-reducing rolls are adjusted apart, and means whereby the endwise-shiftable rolls are shifted endwise simultaneously with and in the same direction as the adjustable web-reducing roll is adjusted.

ll. The combination of ahorizontal roll arranged transversely of the path of the blank or work fed with its web arranged horizontally, in position to operate upon the lower side of the web and upon the inner sides of the heads or flanges of the blank or work, another horizontal roll arranged transversely of the aforesaid path in position to operate upon the upper side of the web and upon the inner sides of the heads or flanges and adjustable toward and from the bottom web-reducing roll, mechanism instrumental in effecting the adjustment of the adjustable webreducing roll, a shaft operatively connected with the said mechanism, endwise-shiftable Vertical or upright side rolls arranged to operate upon the outer sides of the flanges or heads, two slides carrying the different side rolls respectively, means for adjusting the said slides toward or from each other, another shaft parallel with the first-mentioned shaft and operatively connected with the said slide-shifting means, means whereby power is transmitted from the one to the other of the said shafts and whereby the relative speeds of the said shafts can be changed so as to render changeable the ratio of the distance which the adjustable web-reducing roll is shifted to the distance which the side rolls are laterally shifted, means instrumental in shifting the side rolls endwise, and means whereby the operation of the last-mentioned roll-shifting means issimultaneous with and dependent on the adjustment of the adjustable web-reducing roll, and the arrangement of the parts being such that the side rolls are shifted endwise and in the same direction in which the adjustable webreducing roll is adjusted.

l2. In a rolling-mill, a pair of horizontal rolls, means for adjusting them toward and from each other, a side roll, means whereby the adjustment apart of the horizontal rolls imparts a proportionate vertical adjustment to the side roll, and means wherebya lateral adjustment of the side roll may be effected independent of the said other adjustments.

In testimony whereof I sign the foregoing speciiicatiomin the presence of two witnesses, this 5th day of September, 1902, at Cleveland, Ohio.
